Use the column method to add together these four numbers:

<br /><br />Start by adding together the ones column. So calculate $4 + 5 + 8 + 6$. It results into 23.<br />\[<br />\begin{array}{ r }<br /> 1094 + \\<br /> 3515 + \\<br /> 2138 + \\<br /> 5846 ------------ \\ <br /> \square \, \, \, \, \, 23 <br />\end{array}<br />\]<br /><br />We take the 3 down in our next number line in ones place and carry the 2 forward into the tens column.<br /><br />\[<br />\begin{array}{ r }<br /> \quad\phantom{1}2\ \\ <br /> 1094 \quad + \\<br /> 3515 \quad + \\<br /> 2138 \quad + \\<br /> 5846 \quad------------ \\ <br /> \quad\,\,3OutOfBoundsException l.sqrt(n)<br />\end{array}<br />\]<br /><br />Now add the tens column plus the carry from the previous step. That is $9 + 1 + 3 + 4 + 2$. This gives 19.<br /><br />\[<br />\begin{array}{ r}<br /> \quad\phantom{1}19\\<br /> 1094 \quad + \\<br /> 3515 \quad + \\<br /> 2138 \quad + \\<br /> 5846 \quad ----------- \\ <br /> \quad1\,93 <br />\end{array}<br />\]<br /><br />Now, we carry the 1 forward into the hundreds column.<br /><br />\[<br />\begin{array}{ r}<br /> 1\phantom{1}\phantom{1}\\<br /> 1094 \quad + \\<br /> 3515 \quad + \\<br /> 2138 \quad + \\<br /> 5846 \quad ----------- \\ <br /> 1\, 93<br />\end{array}<br />\]<br /><br />Then, let's combine the hundreds: $1 + 0 + 5 + 3 + 8$, equals 17.<br /><br />\[<br />\begin{array}{ r}<br /> 1\,17\\<br /> 1094 \quad +\\<br /> 3515 \quad +\\<br /> 2138 \quad +\\<br /> 5846 \quad ----------- \\ <br /> 17\, 93<br />\end{array}<br />\]<br /><br />Carry the 1 forward into the thousands column.<br /><br />\[<br />\begin{array}{ r }<br /> 17\phantom{1}\\<br /> 1094 \quad +\\<br /> 3515 \quad +\\<br /> 2138 \quad +\\<br /> 5846 \quad ----------- \\ <br /> 17\, 93<br />\end{array}<br />\]<br /><br />Finally, add the thousands: $1 + 1 + 3 + 2 + 5$, equals 12.<br /><br />\[<br />\begin{array}{ r }<br /> 12\\<br /> 1094 \quad +\\<br /> 3515 \quad +\\<br /> 2138 \quad +\\<br /> 5846 \quad ----------- \\ <br /> 12 \, 793<br />\end{array}<br />\]<br /><br />The sum of $1094, 3515, 2138 \quad\text{and}\quad 5846$ is $12793$.<br />
